ADJUSTABLE SIDE BEARING FOR CARS.

SPECIFICATION forming part of Letters Patent No. 711,832, dated October21, 1902.

Application filed Tune 26,1902.

To a/ZZ whom. t 711.601/ concern:

Be it known that I, LESTER O. DENISON, a resident of Anaconda, in thecounty of Deerlodge and State Yof Montana, have invented certain new anduseful Improvements in Adjustable Side Bearings for Cars; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilledin the art to whichit appertains to make and use the same.

My invention relates to an improved adjustable side bearing for cars,the object of the invention being to provide an improved side bearingwhich can be readily and quickly adjusted to give side clearance to thecar, and, further, to provide a side bearing which can be secured uponthe truck-bolster of cars now in use to replace the old expensive andnnsatisfactory devices now commonly employed.

With this object in view the invention'consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in claims.

In the accompanying drawings, Figure lis a side view. Fig. 2 is a topplan view. Fig. 3 is an end view, and Fig. 4: is a view in crosssection.

l represents a bearing-box having lips 2 at each end perforated, asshown, to receive bolts to clamp the box upon the truck-bolster of acar. In box 1 a bearing-block 3 is located and is preferably casthollow, as shown, for cheapness and lightness. This bearing-block restsupon shims 4, which are inserted and removed through au opening 5 in oneside of the box normally closed by a slide 6, beveled at its ends andmounted to slide in grooves 7 in the box and provided with a handheld 8to facilitate the removal of the slide'when it is desired to remove ashim or place an additional one in the box. As the shims are liable tostick in the box,- I provide a small opening 9 in the side thereofopposite to opening 5 to permit the entrance of a cold-chisel orl othertool to dislodge them.

It will thus be seen that with my improvements when it is desired toadjust the bearing it is simply necessary to remove slide 6 and take outor put in the shims, as the case Serial No. 113,267. (No model.)

may be. The car .need not be disturbed in this adjusting operation, andthe shims may be of any desired thickness to secure the properadjustment.

When old'side bearings are removed from trucks,nlybearing can replacethem at greatlyreduced cost, and the expense of adjusting this bearingis only nominal, while with all others the expense of labor necessary toaccomplish the adjustment of side bearings is very great.

A great many slight changes and alterations might be made in the generalform and arrangement of the several parts described without departingfrom my invention, and hence I do not limit myself tothe preciseconstruction set forth, but consider myself at liberty to make suchslight changes and alterations as fairly fall within the spirit andscope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a side bearing, the combination with a box having an openingthrough one of its walls for the admission of shims, of a bearingblockconstructed to rest within the box and on the shims therein.

, 2. In a side bearing, the combination with a box having an opening inits side for the admission of shims, a slide to close said opening and abearing-block'in the box on the shims. y Y

3. In a side bearing, the combination with a box to be secured on atruck-bolster and having an opening in one side for the admission orremoval of shims to adjust the bearing, a slide to close said opening, ahollow bearing-block in the box supported on the shims and said boxhaving an opening in its side for the admission of a tool to dislodgethe shims.

In testimony whereof VI have signed this specification in the presenceof two subscribing witnesses.

LESTER C. DENISON.
